1. A method of determining a downlink transmit power from a base station at a wireless terminal, the base station and the wireless terminal having a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols available for transmission, the method comprising:

  • receiving a cell-specific parameter (PB) signaled by one or more higher layers from the base station; and

    determining a cell-specific ratio (ρ

    B

    A) of a first ratio of traffic data to pilot (T2P) for first OFDM symbols (denoted as ρ

    B) to a second ratio of T2P for second OFDM symbols (denoted as ρ

    A), based on the cell-specific parameter and a number of cell-specific antenna ports configured in the base station.
